Summary

"This trial will look at how blood sugar levels change after trying different sweeteners, using a device that continuously monitors glucose levels."

Who is the study for?
This trial is for healthy adults aged 18 to 70 without diabetes, heart disease, metabolic disorders, or other chronic conditions affecting blood sugar. Participants should not have had major surgeries or be on medications that alter glucose metabolism or taste perception.
What is being tested?
The study tests how different sweeteners (sucralose and sucrose) and controls (salt, water, no stimulation) affect blood sugar levels using continuous glucose monitoring in people with prediabetes.
What are the potential side effects?
Since the interventions involve only tasting sweeteners without ingestion, side effects are minimal but may include potential changes in appetite or minor digestive discomfort.
